1 Introduction to TMF

TMF protects databases in online transaction processing (OLTP) environments. It does

this by managing database transactions, keeping track of database activity through the

use of audit trails, and providing database recovery methods. TMF performs its

functions while sustaining high performance in a high-volume, distributed OLTP

application environment.

To manage large systems or networks efficiently, it is beneficial to transfer many of the

routine management tasks to the computer system or network itself. This manual

describes how to design and code applications that manage TMF.

Management Programming for TMF

TMF supports the Distributed Systems Management (DSM) facilities. In the context of

DSM, a subsystem is a set of processes that manages a cohesive set of objects in the

computer system. A subsystem can be managed by a person using an interactive text

interface like TMFCOM or by a management program that automates operator

functions using the Subsystem Programmatic Interface (SPI) to communicate with the

TMFSERVE process.

What is Management Programming?

Management programming is a way to automate many routine management tasks and

free human operators to do work requiring judgement and creativity.

Many tasks that a program can perform fall into one of two categories: control and

inquiry, or event management. Control and inquiry tasks use commands to change or

inquire about the configuration or status of objects in a system or network. Commands

provide a two-way interface:



A human operator or application program sends a command to a subsystem.



The subsystem performs some action and returns a response to the operator or

application.
